Here is a set of points showing the relationship between the how far a cargo truck is driven and how much it costs to rent it.

(a) How much does it cost to rent the truck and to not drive it anywhere?

(b) What is the independent variable?

(c) How much does the price increase every 10 km driven?

(d) How much does the price increase for every 1 km driven?

(d) What is the rate of change?

(e) How much does it cost to drive 10 km?

(f) How much does it cost to drive 45 km?

(g) How much does it cost to drive 200 km?

(h) How much does it cost to drive ‘x’ km?

(i) What equation can you write in the form $y=mx+b$ that goes through these points?
